Role Playing Games/Types of RPGs

Ok, down to basics, I'll break it down to 4 types for now: futuristic, currently based, historical, or just plain made up. For example, some futuristic RPG's are The fallout series, currently published by Bethesda. side note- I have heard that Bethesda will make a 4th!. OK, then there are currently based RPGs. Some examples are: The Escapist, and SOMEWHAT Heavy Rain... Some historical are: Dragon Age, TES, and others. Anyway, this is enough for now, I will next talk about, (Drum Roll) Text Adventures!.
